BACKGROUND: Globally, social inequalities contribute to elevated sexually transmitted infections (STIs) rates among transgender women. High syphilis prevalence has been documented among transgender women in Latin America. Little is known, however, of syphilis testing uptake among transgender women in Jamaica, where homosexuality is criminalized. The study objective was to understand factors associated with opting-in for syphilis testing and a syphilis infection history among transgender women in Jamaica...

From 1927 to 1942, the Rockefeller Foundation ran a tuberculosis commission in Jamaica that researched the epidemiology of the disease, examined the efficacy of a vaccine with heat-killed tubercle bacilli, and offered basic treatment to tuberculosis sufferers. Drawing upon diaries and scientific writings by the staff employed by the commission, among other sources, this article explores the role that race played in the tuberculosis commission. It assesses how race shaped the research conducted by the commission, how it informed staff interactions and staff/patient relations, and the clash and/or confluence of "imported" and local racial ideas in the commission's work...

Jamaica has earned an international reputation for severe sexual prejudice-perhaps disproportionately so compared to other severely anti-LGBT (lesbian, gay, bisexual, and transgender) societies. Until recently, however, no quantitative empirical research had investigated Jamaica's sexual prejudice, leaving the prejudice poorly understood and methods of reducing it unclear. This article reviews empirical research on Jamaican anti-LGBT prejudice from the past 15 years. It situates Jamaica within the global context, explains the current understanding of the severity and nature of the problem, evaluates solutions currently being explored, and suggests promising strategies based on available evidence...

Background Psychosocial factors interact with adolescent development and affect the ability of HIV-infected adolescents to cope with and adhere to treatment. Aim To evaluate psychosocial outcomes in perinatally HIV-infected adolescents (PHIVAs) in Western Jamaica after psychosocial intervention. Methods The Bright Futures Paediatric Symptom Checklist (BF-PSC) was used for psychological screening of PHIVAs in Western Jamaica. Referred patients were evaluated using the Youth version of the Columbia Impairment Scale (CIS)...

BACKGROUND: Globally, men who have sex with men (MSM) experience social marginalization and criminalization that increase HIV vulnerability by constraining access to HIV prevention and care. People who sell sex also experience criminalization, rights violations, and violence, which elevate HIV exposure. MSM who sell sex may experience intersectional stigma and intensified social marginalization, yet have largely been overlooked in epidemiological and social HIV research. In Jamaica, where same sex practices and sex work are criminalized, scant research has investigated sex selling among MSM, including associations with HIV vulnerability...

Objectives: To determine the relative influence of sociodemographic, socioeconomic, psychosocial, and health variables on health service utilization in the last 12 months. Methods: Data were analyzed for 1,412 men ≥60 years old from a 2012 nationally representative community-based survey in Jamaica. Associations between six health service utilization variables and several explanatory variables were explored. Logistic regression models were used to identify independent predictors of each utilization measure and determine the strengths of associations...

Introduction: The aim of the study was to determine the prevalence of dyslipidemia among primary care patients with hypertension and diabetes in Jamaica and the proportion of patients who achieve recommended targets. Material and methods: An audit of 500 dockets of adult patients with chronic disease attending public primary care clinics in Jamaica was conducted between October and December 2013. Data were collected on patient characteristics including medical history, medications, anthropometry, and lipid profiles (since January 1, 2011)...

INTRODUCTION: Obesity is rising globally and is associated with increased risk of adverse pregnancy outcomes. This study aims to investigate overweight and obesity and its consequences among Jamaican women of reproductive age, particularly development of diabetes, hypertension and the risk of maternal death. MATERIALS AND METHODS: A national lifestyle survey (2007/8) of 1371 women of reproductive age provided data on the prevalence of high BMI, associated risk factors and co-morbidities...

Evolution and population genetic structure of marine species across the Caribbean Sea are shaped by two complex factors: the geological history and the present pattern of marine currents. Characterizing and comparing the genetic structures of codistributed species, such as host-parasite associations, allow discriminating the relative importance of environmental factors and life history traits that influenced gene flow and demographic events. Using microsatellite and Cytochrome Oxidase I markers, we investigated if a host-parasite pair (the heart urchin Meoma ventricosa and its parasitic pea crab Dissodactylus primitivus) exhibits comparable population genetic structures in the Caribbean Sea and how the observed patterns match connectivity regions from predictive models and other taxa...

This paper provides early instrumental data recovered for 20 countries of Latin-America and the Caribbean (Argentina, Bahamas, Belize, Brazil, British Guiana, Chile, Colombia, Costa Rica, Cuba, Ecuador, France (Martinique and Guadalupe), Guatemala, Jamaica, Mexico, Nicaragua, Panama, Peru, Puerto Rico, El Salvador and Suriname) during the 18th and 19th centuries. The main meteorological variables retrieved were air temperature, atmospheric pressure, and precipitation, but other variables, such as humidity, wind direction, and state of the sky were retrieved when possible...

OBJECTIVES: To explore putative associations between specific variants in either the glutathione S-transferase (GST), haptoglobin (HP), or uridine 5'-diphospho-glucuronosyltransferase 1A1 (UGT1A1) genes and clinically important phenotypes in sickle cell anaemia (HbSS). METHODS: Three hundred and seventy-one HbSS participants were recruited from the Sickle Cell Clinic of the Sickle Cell Unit at the University of the West Indies, Kingston, Jamaica. Markers within four GST superfamily genes, the HP gene, and the UGT1A1 gene were analyzed using PCR-based assays...

Physical punishment has received worldwide attention because of its negative impact on children's cognitive and social development and its implications for children's rights. Using UNICEF Multiple Indicator Cluster Surveys 4 and 5 data, we assessed the associations between positive discipline, harsh physical punishment, physical punishment and psychological aggression and preschoolers' literacy skills in 5628 preschool-aged children and their caregivers in the developing nations of Belize, the Dominican Republic, Guyana, Jamaica and Suriname...

Moringa oleifera trees grow well in Jamaica and their parts are popularly used locally for various purposes and ailments. Antioxidant activities in Moringa oleifera samples from different parts of the world have different ranges. This study was initiated to determine the antioxidant activity of Moringa oleifera grown in Jamaica. Dried and milled Moringa oleifera leaves were extracted with ethanol/water (4:1) followed by a series of liquid-liquid extractions. The antioxidant capacities of all fractions were tested using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay...

Health communication and social mobilization efforts to improve the public's knowledge, attitudes, and practices (KAP) regarding Ebola virus disease (Ebola) were important in controlling the 2014-2016 Ebola epidemic in Guinea (1), which resulted in 3,814 reported Ebola cases and 2,544 deaths.* Most Ebola cases in Guinea resulted from the washing and touching of persons and corpses infected with Ebola without adequate infection control precautions at home, at funerals, and in health facilities (2,3). As the 18-month epidemic waned in August 2015, Ebola KAP were assessed in a survey among residents of Guinea recruited through multistage cluster sampling procedures in the nation's eight administrative regions (Boké, Conakry, Faranah, Kankan, Kindia, Labé, Mamou, and Nzérékoré)...

BACKGROUND: Species of the scyphozoan family Pelagiidae (e.g., Pelagia noctiluca, Chrysaora quinquecirrha) are well-known for impacting fisheries, aquaculture, and tourism, especially for the painful sting they can inflict on swimmers. However, historical taxonomic uncertainty at the genus (e.g., new genus Mawia) and species levels hinders progress in studying their biology and evolutionary adaptations that make them nuisance species, as well as ability to understand and/or mitigate their ecological and economic impacts...

It was previously demonstrated that differentiation of some established breast epithelial cell lines requires confluence and stimulation with hydrocortisone, insulin and prolactin inducers. We and others previously demonstrated that E-cadherin engagement, which is favored under conditions of confluence, increases the levels and activity of the Rac small GTPase. To investigate the functional relationship between the transforming ability of Rac and its role as an integral component of the differentiative E-cadherin signaling pathway, we introduced a mutationally activated form of Rac, Rac(V12), into the mouse breast epithelium-derived cell line, HC11...

BACKGROUND: HIV/AIDS remains a global public health challenge, especially in sub-Saharan Africa and the Caribbean. Sexual risk behaviors among HIV-positive persons place their partners at risk for HIV transmission and other sexually transmitted infections. Stopping transmission acts among HIV-positive people is crucial in reversing HIV incidence. OBJECTIVE: This study aimed to assess the prevalence and predictors of sexual risk behaviors among HIV-positive individuals in clinical care in Northwestern Jamaica...
